While I was reading some various text below two things came up over and over like them in a rule.

  1. Early this morning (Ex. 4~5 AM)

  2. Earlier this month (Ex. 1~5 Nov.)

If "early" and "earlier" were exchanged, would those sentences still be correct, and are the meanings the same as before?

  1. Early this morning = earlier this morning?

  2. Earlier this month = early this month?

  • "Earlier" is the comparative of the adverb "early" and one can't replace the other without changing the meaning. It is better to read your texts more carefully.

    At first this question seems to be nonsense. Of course there is a distinction between an adjective/adverb and its comparative. However, speaking as a Brit, I notice a phenomenon in US English that seems to confuse the two. I speak of 'old' and 'older'. For PC reasons an 'old' person may be described as an 'older' person in the US. The distinction has become blurred. This is not the case in the UK. Could this be part of the same phenomenon?

    Contrast I will wake up early this morning and I will wake up earlier this morning. The first is a simple statement that I will wake up early. The second is a comparison: perhaps I will wake up earlier than my friend, or I will wake up earlier than I did yesterday. Nov 3, 2015 at 12:50
  • @Rathony I know the difference between them and understand what you said. But I thought it's strange to use "earlier" with "month" even there is nothing to compared with it. And I had another question about "morning" like 'Earlier morning is correct?'.

    @user145679 The "earlier" example, strictly speaking, only works if the context tells the audience the target of the comparison (friend, yesterday, etc.). Nov 3, 2015 at 17:05

Part 1 of the question

The questioner says:

While I was reading some various text, below two things came up over and over like them in a rule.

Early this morning Earlier this month

First of all let us examine the claim quantitatively.

Google ngram: early this morning,earlier this month,earlier this morning,early this month

enter image description here

By examining the graph there does seem to be some validity to the 'rule'.

'early this morning' appears roughly 5 times as often as 'earlier this morning'.

'earlier this month' appears roughly 4 times as often as 'early this month'.

Suggested explanation

A thoroughly researched answer would take many hours and involve the analysis of a great deal of text. Instead I'll guess.

I believe that the explanation simply relates to what we are most likely to talk about.

Early/earlier this morning

If I speak to someone during the day about my morning exploits, I may be talking (a) during the morning (b) during the afternoon (c) during the evening or (e) at night.

Only in the first case does it usually make sense to talk about things that happened 'earlier this morning'. In the other cases we would be more likely to discuss what happened 'early this morning'. Thus there are simply more occasions during a day when the latter is appropriate. (Note that this explanation relates to Hot Licks' answer and suffers from some of the same problems)

Early/earlier this month

In this case a month is not divided into arbitrary categories such as month-morning, month-afternoon etc. So when you are in a month, any story you relate refers to 'earlier'.

Note I do not claim this as an authoritative answer. It is simply a hypothesis.

Part 2 of the question

if "early" and "earlier" were exchanged, are those still correct and are the meanings same as before?

Early this moring = earlier this morning? Earlier this month = early this month?

The simple answer is that you can exchange the words and the phrases remain grammatically correct.

As to whether the meanings are the same: Without context it is difficult to say. On the face of it the meanings are different for the same reason that 'big' and 'bigger' are different words.

However English is a context dependent language so it is possible that a particular context could cause the fragments to be equivalent.

  • I think the use is idiomatic, as I explained in my answer. In any case, answers to this are mostly opinion-based. Good work, though. BTW, I can't find any reliable info on "that" as a conjunction. Mind if I ask a question and use the example sentence? Nov 3, 2015 at 15:04
  • Great research! And your explanation is easy and clear to understand. You really caught my point of the question. Thank you so much!

  • @michael_timofeev - Go ahead. I give blanket permission to anyone to use or quote anything I post. It is public anyway so I don't mind if it is quoted. Nov 3, 2015 at 17:58

I am an AmE speaker and I have heard people use the expressions interchangeably to mean the same thing. The meaning is that something happened earlier in the day or month and tends to be idiomatic. So unfortunately, when someone says "Early this morning, I took the train to work." They could mean the train left at 5am or just mean that they took a train in the morning. Same with earlier this morning. The context, though is important, so if the discussion centered around the sequence of events in the morning a speaker is more likely to not be idiomatic and use "earlier."

Here is an idiomatic use example:

"What did you do today?" "Well, let's see, early / earlier this morning, I went to the gym and tried out that new racquet I got."

Here is a precise use example: "You look happy. What did you do today?" "Around lunch, I got a call from Stu. We got the contract from NASA. Earlier this morning I had a good workout in the pool, so yeah, I guess I'm happy."

I have heard "earlier" used to talk about a bus in this way: "We need to catch the earlier bus." and the speaker wasn't talking about a bus that left at a time earlier than another...they meant "We need to catch the bus that leaves early in the morning." This happened during conversation and I understood from the context what she meant.

You asked if one can exchange the words and retain the meaning. Technically, no, however as I discussed above, people (AmE speakers I have heard) will exchange them. It would be interesting to hear from other AmE speakers. I recall this being used in the Southern US.

  • Thanks for correcting my question and for your answer. But I'm still confused. For example, I got a phone call this morning, it was just right after getting to the office and I want to emphasize it was too early then can I say "I got a phone call early this morning"?

  • Yes, I'm British and I see this as a US phenomenon. In the case of, "We need to catch the earlier bus" I can't imagine anyone I know using this to refer to the early bus. For me it would definitely imply that there were two buses and you were talking about the one that leaves first. Nov 3, 2015 at 21:53
  • @user145679 yes, you can say that. Nov 4, 2015 at 0:14
  • @chaslyfromUK I've noticed many Americanisms come from not knowing the grammar, or from places where the education level is "different" than other regions. Nov 4, 2015 at 0:16

"Early this morning" refers to a time in the early morning (which of course is a relative concept, depending on your culture and habits). "Now" may be the morning, afternoon, or evening.

"Earlier this morning" refers to a time prior to "now" (which is presumably morning or early afternoon) but which was after midnight or maybe 3AM (depending on culture and habits).

(Note that, per Chasly's comment, the above assumes there is no other immediate context that would tend to define/constrain "earlier", as in "Early this morning I had my breakfast and even earlier this morning I had a shower." In this latter case "earlier" is understood to have it's "usual" meaning relative to the "early" clause in the context.)

As Nathanial says in a comment above, "earlier" only works when there is some context to answer "earlier than what?". If someone comes up to you and says "Earlier this morning I did X", without any prior discussion or other source of context, one can reasonably assume that the reference point is "now". If they first discuss something they did an hour ago, the reference point may well be "now" minus one hour (though this is not 100% guaranteed).

But the point is that it does "make sense" -- it's not a set of arbitrary rules you need to memorize, but rather you just need to analyze the logic, context included. (Though, as with everything having to do with the English language, one needs to be wary of being too rigid and strict in the application of "logic".)

  • @Rathony -- ??? That makes no sense. (I mean, I can't parse it into anything meaningful.)

  • @Rathony - Where did I say that "earlier" means midnight to 3AM?

  • Sorry, I will rephrase. I don't think "earlier" necessarily refers to an earlier time compared with now. It is only meaningful when compared with a specific time in mind.

  • @Rathony - You don't think that "earlier this morning" means "at a time prior to now but still in 'this morning'"? You're still not making sense.

  • Why would you use "earlier" instead of "early" when you refer to a time before now and still in this morning? Do you mean you can't use "early" in the following example? (I can say at 9 AM) "I woke up early this morning."
